Magnetism does not affect the resistance of a conductor. The factors affecting resistance are the conductor's length, cross-sectional area, and resistivity. As resistivity is affected by temperature, temperature indirectly affects resistance.
However, the changing magnetic field surrounding a conductor carrying an AC current causes the current to flow closer to the surface rather than being distributed throughout the cross-section of the conductor. The greater the frequency, the greater this effect. This has the equivalent effect of reducing the cross-sectional area of the conductor, causing its resistance to rise. This is misleadingly called the 'AC resistance' of the conductor!

What did Faraday discover about magnets?
Michael Farady is best known for his work in the field of electricity and magnetism. He discovered the effect of magnetism on light, discovered and named Diamagnetism, the behavior of substances in magnetic fields and he was the first to produce an electric current from
What is the magnetism of an emerald?
there is no magnetism to an emerald
Is paleomagnetism the study of ancient magnetism?
Paleomagnetism is the study of the magnetism of ancient rocks. In principle, it was the study of ancient magnetism
What is the sure test of magnetism?
The sure test of magnetism is REPULSION .
What is difference between residual magnetism and retentivity?
Residual magnetism and remanence are the same thing. The term residual magnetism is often used in engineering applications. Both terms describe the magnetization, and measure of that magnetism, left behind in a ferromagnetic material after the external magnetic field is removed.
Does magnetism have an effect on gravity?
No.
